To all whom it may concern:

Be. .it known that I, tti-mucus M. Cnooii, a citizen ot the UnitedStates, residing at- Chicago, in the county otl Cook and State ofIllinois, have invented a ei'tain new and ufetul Improvement inTime-Stamps, of which the, iollowing is a full7 clear, concise7 andexact description, reference being' had to the accompanving drawing',forming a part ot this specification.

rIhis invention relates to improvements in time stamps, and moreparticularly to portable `stamps *arrying a horologic motor foroperating the impression mechanism and having gage parts adapted toadjust the impression mechanism relative to the surface to be, stampedto insurer a clear and legible impression thereon.

lt is desirable to use port-able stamps of this character in repairshops and other places where job work is done, to keep an accurateaccount ot the time spent by employees at their work, when not under thesupervision ot their employer. In such cases where the stamp isintrusted to the care of the employee, it is desirable to have meanswhereby the motor mechanism cannot be moved or the character of theimpression to be made by the stamp altered except by the one havinglauthority and supervision. It

also desirable to provide means for braking;l or lockingl the separableimpression mechanism when said mechanism is disengaged from the motormechanism.

(ne ot the objects oi the present invention is to provide a settingdevice tor the stamp, which will be susceptible ot' being operatedsolely by a specially formed implement- Another object ot the inventionis to provide means tor locking` the impression mechanism when the sameis operated to make an impression.

A further object ot the inventionis to provide means tor yieldinglymounting the clock mechanism or horologic motor upon its supportingtrame, so that when the stamp is being operated, the impact or jar uponthe clock mechanism will be relieved.

l further objectI of my invention is to provide means torinsuring theproper movement ot' the impression mechanism in making' an impression.and to provide ett'ective means for `guiding' the same.

The ther objects and special tentures of my invention will more fullyappear from the accompanying drawings and description, in which areillustrated and described embodiments ot my invention which I haveworked out. tor commercial purposes, and in which lil-:e referencecharacters indicate similar parts throughout the several tigures.

In the drawings: Figure l is a sectional elevation ot my in'iprovedstamp; Fig. 2 is a cross section on the line 2 2 oi" Fig. l, looking inthe direction of the arrows; Fig. 3 is a view of the stamp from thebottom, showing the bi'ake for the dials; Fig. J.- is a sectional viewon the line et of Fig'. l, showing' one arrangement.- ot the impressionmechanism; Fig'. is a detail sectional view ot one `torni ot thedrivingy arbor and synchronizing device; Fig. is a sectional view on theline G-( of Fig'. l, showingv the resilient mounting' tor the motor',Fig. T is an enlarged sectional view on the line TAT ot Fig. i; Fig. 8is a detail view of the selective setting' device; Fig. 9 is a partialsectional view ot' the locking device,v viewing the impression mechanismtrom the bottom; Fig. l0 is a side view thereof; Fig'. ll is a sectionalview on the line llell ot Fig'. f): Fig. 1'2 is a perspective view ofthe inclosing cap or casing tor the motor; Fig. 1?; is a detail viewshowing the arrangement ot the cups t'or the inking pads and dials; Fig.le is a view ot' the bottom of the tumbler. showing' Celluloid coveringfor the dials.'

The stamp illustrated in the drawing." has a stationary trame providedwith gage parts I. adapted to support the stamp and serving' to bearupon the surt'ace to be iinpressed to adjust the impression mechanism tosaid sur't'ace. Said `trame consists ot' two upright portions and atable '2 secured thereto in any suitable mani er. Mounted upon the tableis any suitable clock mechanism or horologic motor El, said mechanismVportion of the stamp.

being represented as a clock train having the usual main spring L10 andwinding stem .4;1. The motor mechanism is resiliently mounted upon thesprings et, interposed between the table 2 and the plate 5 of the clockmechanism, and retained in position by studs t, preferably secured uponthe top of the table 2, as shown in Fig. 7. The upper ends of the studsextend through holes in the bottom plate 5, and are engaged by plates T,the slotted ends of the plates entering' small annular recesses formedin the studs, whereby the clock mechanism is resiliently held inposition upon the table 2 against the springs 4. The plates 7 are heldin place by engagement with the walls of the inclosing casing or cap S,which rests upon the table Q. r1`he cap or casing S is preferably formedor stamped from a single piece of sheet metal, the sides and endsthereof being` drawn down, whereby the same presents a perfectly smoothexterior, without seam or joint, as shown in Fig. 1Q, and is susceptibleof receiving' a high polish. Openings are formed in the top of thecasing for the central tube 15 and for the selective setter 31 andwinding stem 4:1. A slot is also formed in one end thereof, throughwhich the regulating finger et? may be manipulated for regulating themotor mechanism. The transverse ends or walls of the casing are adaptedto rest upon the table 2, and the longitudinal walls #tI-l thereofextend to lie iush with and snug against the longitudinal sides of thetableQ, being secured thereto by screws lll or in any suitable manner.The walls of the cap 8 are adapted to engage the plates 7 to retain theplates in engagement with the pins G, when the casing is in position. ltwill be thus seen that the motor mechanism may be readily removed fromthe table 2 after the casing has been removed therefrom, by withdrawing'the plates T from engagement with the 'retailiingl pins C. Theparticular construction ofthe casing or cap 8 may be varied, and thearrangement of the springs 4 and pins 6, and the method of securing themotor mechanism thereto may be changed, without departing from thespirit of my invention. Below the table Q is a plate or frame 9, whichcarries the impression mechanism 4S and constitutes the tumbler orreversible The tumbler is mounted upon a rod 10, slidable within theslots 11 in the stationary frame and connected with a handle 13 by thearms 141-. These arms are preferably formed or stamped from a singlepiece or strip of sheetmetal and bent into a U-shaped piece, having theends thereof engaging the rod 10, as shown in Fig. 1. The handle 13 isslidable upon a tube 15, which normally elevates the handle, and holdsthe operative face of the impression mechanism in firm engagement withthe inking pads. The arrangement of the impression mechanism and inkingpads will be hereinafter described.

The movable plate or tumbler 9 carries cams 17, which are arranged toengage studs 1S upon the stationary frame and revolve or reverse saidtumbler when it is lowered. To prevent wear upon the studs or pins 1S,and the lost motion due to wear upon the pins from constant cont-act ofsaid pins with the cam faces 17, 1T of the movable plate 9, I providecam rollers or sleeves 65, loosely mounted upon the pins or studs 18, asshown in Fig. 19, which are adapted to revolve and reduce to a minimumthe friction upon the cam faces and upon the pins 1S, in making animpression, A pair of cam rollers is also mounted upon the rod 10, asshown in Figs. 1 and 18.

1t is important that the tumbler or movable frame carrying theimpression mechanism move with a minimum frictional engagement of theparts, and without appreciable lost motion or irregular movementthereof. Any lost motion or irregular movement of said movable printingmechanism would tend to prevent the impression mechanism from properlyengaging the motor mechanism, and the revoluble inking pads carried bythe stationary frame would not be properly engaged by the revolubleimpression mechanism; and, moreover, the device would not be properlysynchronized. The cam roller above described permits the tumbler l() tobe nicely adjusted, so that the revoluble impression mechanism carriedby the tumbler properly engages the revoluble pads carried by thestationary frame, and the impression mechanism is properly -synchronizedwith the motor mechanism, said cam rollers also preventing wear upon thepins 18 and cam faces 17 and the consequent lost motion and irregularmovement of the tumbler 10.

Upon the movable frame are journaled suitable printing' disks or dials19, one of said disks being connected with the driving arbor 20 of theclock mechanism and operating the other disks through suitable gearing21. A setting stem 20' extends through the driving arbor' and isprovided with a suitable setting handle 20". The connection between saiddriving arbor and the revolving disks of the impression mechanism iseffected by a pin 2Q, carried by said arbor eccentrically of its axisand entering a recess or notch in a disk 3, fastened to the arbor of oneof said revoluble disks, so that when the impression mechanism islowered to make an impression, the pin will be withdrawn from the diskand thereby disconnect the revoluble disk from the horologic motor. Vhenthe impression mechanism is raised, after having been lowered to make animpression, the pin will engage an 'incliued wall at the edge ot saidrecess and thereby turn the disk until the movementv which saidin'ipression mechanism has lost while disconnected from the clockmechanis-m is compensated for. and the impression mechanism thussynchronized with the clock mechanism. (See Fig. 5.)

in the Yform ot my invention shown in Figs. 153 to Q0. inclusive, lpreferably provide upon the bottom or under side ot' the table 2 a thinsheet-metal strip 45, upon which is secured the inking pad -lG ot 'feltor any suitable material, covered wit-h a thin linen cloth l?. adaptedto engage the tace ot the impression mechanism i8. which preferably madeof rubber and carried upon the tumbler or reversible plate il, a thinstrip ot i ietal being also disposed between said plat and thein'ipression mechanism i8. as shown in Fig. 18. The metal strips -l and1l-9 have annular tlanges 50 struck up therelirom. as shown in Fig. 1?).Disposed within said annular Vllanges are small metal cups 51. 5l. thecups carried upon the table 2 being adapted to contain inking pads lo,preterably made ot telt. the annular flanges 5() being adapted toprevent the ink with which said pads are saturated trom oozingtheretrom. owing to the impact ot the tun'ibler 9 with said pads. andescaping into the motor or other mechanism ot' the stamp. @ne ot saidcups is secured to the arbor 20 ot' the horologic motor. and carriesnear the periphery thereo't'. the downwardly extending pin 22. which isadapted to engage the beveled surl'aces tormed upon the tace ot' theoppositely disposed cup carried by the tumbler t). au aperture 53 beingformed in the bottom ot said beveled surtaces` in which said pin isnormally adapted to rest. A pointer 54C 1s disposed transversely withreference to l said beveled depressions in said last menk by the table2.

tioned cup. The pin is adapted to engage the beveled surfaces 52 tosynchronize the impression mechanism with the horologic motor mechanismatter an impression has been made. and is also adapted to drive the cupwith which it engages. the other ot' said cups larried by 'the tumbler 9being driven by a suitable gearing 21. as shown in Fig. 1V. The cups 51carried by the table which are not engaged by the arbor 20, are looselypivoted upon said table, and are adapted to revolve with the cupscarried ,y the tumbler 9.

1n the form shown in Fig. 20 it will be noted that the small hand orpointer 55 is adapted to indicate the A. M. or P. M., the indicator 56indicating `the hour, and the hand or indicator 5l indicating theminute. lt will also be noted thatthe particular construction ot thesynchronizing device pei'- mits the last-mentioned hand or indi"ator toextend the -full width of the cup 52. The month. day and yeaQ are prete'ably mounted upon ribbons 2T. adapted to be moved by hand, by means ofthe wheels The printing disks or other printing elements are pret'erablymade ot resilient material, such as rubber, so thm when an impression isbeing made the l'ace of the impression mechanism will yield to conformto the surface being impressed, and thereby insure a good impression.

l'vheu it is desired that the stamp impress matter in addition to thetime. the type or dies t'or printing the additional matter may bemounted upon the movable 'frame in any suitable vay, ln the presentinstance the revoluble pri iting dies are adapted to print arrowsl whichindicate the time upon dialsI impressed b fv the stationary portionsot', and being mounted upon the plate ot the movable trame. l'lowever,this way ot printing the time is not essential to my invention. and anyother desired torm of printing device may be used. The gearing Q1 Yforrotating the cups carried by the tumbler Sl is preferably mountedbetween plates 5T and 5S. the plate 5S having dials Q5 formed thereon.over which revolve hands Q6 carried by the arbors of the movableprinting dies or cups 5i. These hands indicate upon the dial the timeadapted to be printed by the stamp and assist in setting the stamp. A.Celluloid covering (3l prete 'ably provided t'or the dials Q7. a thinsheet-metal strip (SQ. having apertures opposite said dials. beingsecured to the plate 58, the celluloid covering (il being disposedbetween said sheetmetal plate (32 and the plate 5S. as shown in Figs.lland l5. Carried by the tumbler 9 are alining pins 59, adapted toentei' cups or sockets (S0. carried upon the bottom of the table 2. saidpins and sockets being adapted to co-act to bring the tumbler S) intoproper relation with the revolving cups 5lV carried vpon the arbor oli'one of the revoluble printing dies is carried a brake wheel 2t)t shownin Fig. 9). which is engaged b v the tree end ot' a sp 'ing 3l). pivotedto the tumbler 9. while the impression mechanism is disconnected fromthe horologic motor to prevent said revoluble dies t'romaccidentallyturning in making an impression. should the stamp be 'arelessly placedupon or removed :trom the tace ol: the article being impressed. Adownwardly extending pin 3l is carried upon the under side ot' thestationary trame or table 2, said pin extending throughthe tumbler iland being adapted to engage the spring or brake 3l). to hold same lromengagement with the brake wheel 2.() when the impression mechanism isattached to the motor mechanism. as shown in VFig. 1.

lt is ot'ten desirable to plac a stamp oll this kind in the hands ot anemploys-)e t'or the purpose ot' keeping an accurate check upon the timeoccupied by him in performing his duties, independent of any supervisionupon the part of the employer. To prevent manipulation of the motormechanism by unauthorized parties, provide a modified setting devicewhich takes the form of a selective setter or specially formed device orkey, by means of which the clock mechanism or horologic motor may beoperated. The modified form setting stem and such a selective setter areshovvn in Fig. S. The setting stem 20 is entirely inclosed wit-hin thecasing 3, and carries a pinion 32, which is accessible only through theopening in an internal gear 33, mounted in the casing. The key orselective setter 34 is necessary for operating the setting stem, and hastluted shank adapted to be inserted through the opening in the internalgear 33 and mesh With the pinion 32 on the setting stem. When the key isin position it may be turned to operate the setting stem. 1t will beunderstood that the construct-ion of said selective setting device andspecially formed instrumentor key may be varied vvithout departing fromthe spirit of my invention, and said selective device, for operatinginternal mechanism, may be adapted for use in many different ivays andin combination vvith other structures than that above described. henthis kind of setting device is used in a stamp like that shown herein,it is necessary to lock the impression mechanism vvheu it isdisconnected from the clock mechanism to prevent the impressionmechanism being turned independently of the motor mechanism and therecord or character of the impression adapted to be made thereby thusfalsified. Such a lock may be constructed as shown in Figs. 9 to 11. Aperipherally notched Wheel 35 is fastened upon the arbor of one of therevoluble dies and is adapted to be engaged by a pavvl 36, Which iscarried by a cam 37, said cam being pivoted upon the rod 10. Thile theimpression mechanism and the clock mechanism are connected, the cam isengaged by a pin 3S, carried by the stationary frame or table 2,vvhereby said pavvl is held out of engagement vvith the locking Wheelbut vvhen said impression mechanism is disconnected from said clockmechanism, the cam is engaged by the studs 1S upon the stationary frame,and thereby moved to carry said pavvl into engagement With said Wheel,and thus lock the impression mechanism.

Although the clock mechanism or horologic motor is herein shown asmounted upon the stationary frame, it may be arranged upon the movableframe. By arranging the motor upon the springs, the jar thereon when thestamp is operated vvill be relieved.

The several features of construction, combination and arrangement ofparts herein set forth are merely illustrative of one Way of embodyingthe invention, and it is to be understood thatI various changes may bemade therein Witnout in any Way departing from the invention as setforth in the claims appended hereto. Moreover, the features of myinvention vvhich are claimed are applica ble to many forms of timestamps.

I do not claim herein to be the inventor of the generic feature ofresiliently mounting the motor upon the stationary frame, nor of thegeneric feature of providing guide-posts on the stationary frame forpositioning the horologic motor and maintaining the same in position.Neither do I claim to be the inventor of the generic feature ofproviding a resilient mounting in the form of springs for the motor orin the form of springs or other resilient mounting surrounding saidguide-posts, or in combination with said guide-posts, these featureshaving beenA invented by Charles S.
